[AgileWiki] 2 problems, one unhappy camper

[Bill la F. <bil...@su...>]

The code needs more eyes on it. But then, this is a pretty new set of 
code. Problems exist here and there, I'm sure. And there are not too 
many folk yet with an in-depth understanding.

Lets start with the easy problem. I had "cleaned up" some code a while 
back in AwServlet, removing some attributes. Now occasionally we get 
errors like client attribute missing. I've thought about this for some 
time and believe the problem is due to timeouts (timer is currently 20 
min on a browser session). So its time and past time that I put back the 
original code.

The second problem is more serious, though fixable with only a moderate 
effort. AW supports multi-threading of queries but single-threads when 
there is an update. But queries update caches. Most of the caches handle 
this, but I don't see any synchronization locks in TKS to lock accesses 
to the tks Table. So the tks Table cache will get corrupted, especially 
now that we are getting more activity on agilewiki.org.

One of the big advantages of open source is the many eyes on the code. 
But this requires folk to dig in and ask dumb questions. We'll get 
there, the number of interested developers is growing. But we really 
need more dumb questions. They help with writing good documentation and 
they help in finding "obvious" flaws. Remember, just because the code 
works doesn't mean that it is anywhere near correct.

Your help will always be needed and appreciated.
